They are made on a quite small cold header machine which shapes the wire 
and bends it to size.  If you can picture what the old ticker tape 
machines looked like, they look something like that and are actually 
covered by a transparent dome so you can see the mechanism.  You have 
wire going in one side and pins coming out the chute on the other side.  
At least the ones in our factory were that way back about 1962 when I 
saw them.  I'd expect there are other ways as well.

I would probably get a jewelers rolling mill to make the half-round 
wire, then just bend them.  The bending is the easy part.
